Abstract

The invention relates to a pixel signal conversion method and device. According to an initial first subpixel signal, an initial second subpixel signal and an initial third subpixel signal in a pixel signal, a corresponding first stimulus value signal, a corresponding second stimulus value signal, and a corresponding third stimulus value signal are acquired; according to a second minimal value in astimulus value signal set undergone gaining processing, a fourth subpixel signal is acquired; according to a difference between the stimulus value signal and a corresponding fourth stimulus value signal, a conversion first subpixel signal, a conversion second subpixel signal and a conversion third subpixel signal are acquired; and the conversion first subpixel signal, the conversion second subpixel signal, the conversion third subpixel signal and the fourth subpixel signal are used as converted pixel signals. When the converted pixel signals are applied to a mixed color display consisting ofW, R, G and B four-color subpixels, the display effect is more approximate to actual presentation of original R, G and B mixed colors, the defect of large view color shift is overcome, and the displayeffect is better.

Description

technical field [0001] The present application relates to the field of liquid crystal display technology, in particular to a pixel signal conversion method and device. Background technique [0002] In a traditional liquid crystal display, the three-color light sources generated by the three sub-pixels of R (Red), G (Green), and B (Blue) are generally mixed to produce the desired display color. R, G, and B three-color light sources are absorbed by the photoresist material of the three sub-pixels of R, G, and B to absorb the light bands of the non-R, G, and B sub-pixel units, so that the three sub-pixels of R, G, and B produce corresponding R, G, B three-color light source. [0003] With the improvement of the resolution of the liquid crystal display, the increase of sub-pixels superimposes the decrease of the aperture ratio of the pixel corresponding to the sub-pixels, resulting in the loss of the transmittance of the high-resolution display and the decrease of the light eff...
